An arthropod is an invertebrate animal having an exoskeleton, a segmented body, and jointed appendages. Arthropods include all insects, arachnids, and crustaceans. The USGS Native Bee Inventory and Monitoring Program designs and develops large and small-scale surveys and identification tools for native bees. A vital aspect of the program is to create accurate and detailed pictures of native bees as well as the plants and insects they interact with.
On their 1200+ Flickr photostream, the USGS Bee Inventory and Monitoring Lab has uploaded an astounding collection of macro photographs that you can see in full resolution. Here are 40 of those pictures.
